Behind the Photos
Return air rebuild, Hoffman Estates
The old furnace was starving for air through a single small return, which made it noisy and caused high-limit trips. We installed a new Lennox furnace with an oversized return drop and filter rack, which lowered static pressure and let the blower run quieter.
Ductless mini-split, Hanover Park
A room added over the garage never got enough heat from the main ductwork. A Bosch cold-climate ductless heat pump now heats it on its own thermostat and cools it in summer, without new ducts.
Boiler replacement, Streamwood
A cast-iron hot-water boiler with new near-boiler piping. Nicor Gas offers $350 for 95%+ AFUE boilers and $500 for combination boilers, which we list on the quote when the project qualifies.

How We Approach Every Project
The photos on this page are real jobs completed by Pure Comfort Heating and Cooling technicians in Streamwood, Bartlett, Hoffman Estates, Elgin, Hanover Park, Roselle and nearby towns. Each one followed the same process, whether it was a single furnace swap or a complete system replacement.
Sized and planned before we start
Every replacement starts with a load calculation, so the new equipment matches your home instead of copying the size of the old unit. We review ductwork, venting, gas piping and electrical service, then give you upfront, flat-rate pricing in writing. Where a village permit is required, we handle it.
Clean, careful installation
Our installers wear shoe covers, lay drop cloths and protect the work area. We haul away the old equipment, seal and support new venting and line sets, and leave the mechanical room cleaner than we found it. Most furnace-only or AC-only installations are finished in four to six hours, and a complete system usually takes seven to ten hours.
Tested and explained
Before we leave, we start the system, test it and walk you through the new equipment and thermostat. Lennox equipment carries a 10-year parts warranty, and we back our installation work with our own labor warranty. If something does not look right afterward, call us and we will make it right.
Financing and follow-up
Financing is available through Service Finance, from 0% APR on select Lennox systems during Lennox promotions to longer terms with interest for a lower monthly payment, typically with $0 down on approved credit. After installation, a yearly tune-up keeps the new system running at its best, and our Comfort Club plans make that easy to remember.
